Investigators Cite Track Flaw in England Train Derailment

A track geometry irregularity was visible in CCTV images immediately before a passenger train derailed near Lewes, England, seriously injuring two people. Investigators stated that the irregularity existed on the approach to the derailment point prior to the accident. Evidence of previous track maintenance activity was also noted in the area.

The incident happened during a period of sustained high temperatures across Britain. The ongoing investigation is considering various factors, including the effectiveness of hot weather mitigation measures and the condition of the train, track, and embankment. The railway embankment at the site is constructed of material known to be sensitive to changes in water content. While no significant embankment slip prior to the accident has been evidenced, some prior movement had occurred.
